I have recently obtained a quantity of 16 x 2 line LED backlit LCD's
for next to nothing. Problem is that the data is rather thin. Type is
PVC160202PYL03 (PVC160202PGN). Who is the manufacturer and where can
I get programming data.

'LCD meter type lcd data sheet'
1999\02\11@130653 by Jon Petty
picon face
Hi

I am looking for a LCD meter type lcd data sheet the part number looks like
T2001-LCD. It is used in a meter and is 3.5 digit with HOLD, PEAK, C, F etc.
It has 24 pins and 2 planes. I am not sure how to drive this thing. I have a
legend of characters and thats it.

Can anyone point me in the right direction?

'[OT]: I2C [MDL(S) 16265] LCD Datasheet anyone?'

Hi,

I have a 2x16 LCD display which has an I2C interface but I cannot obtain a
datasheet (in terms of software control) for it anywhere. I know it is made
by Varitronix but they do not have the information on their site.

Does anyone have an appropriate "how to drive it" datasheet ?

I have mailed Varitronix regarding this, also, but thought it might be
quicker to ask you good people.

Best regards,

Dan

Hi,

On the Varitronix site there is a datasheet regarding physical information
for this device...."MDL(S)16265 I2C" and it definately shows SDA and SCL on
the pinout. I was told it was some kind of Sharp interface and that it was
also going obsolete but I was hoping someone might have used one for a
sparse I/O project and have a datasheet.

There is no piggy-back and there are only 6 pins on the edge connector so
it cannot be the standard Hitachi type. AFAIK, these are power (3V, 0V),
contrast, backlight +, SCL and SDA.

Regards,
Dan

'[PICLIST] LCD Data'
2001\03\28@181103 by James Paul
flavicon
face
All,

It seems that several people over the past few months have had one
question or another about LCD's.  Both Graphic and Character.  I
know there is quite a few sites out there with Character based
information on them, but I see very few (read none) that have any
info on Graphic displays like the ones salvaged from old notebook
computers.   So, my proposal here is if you have any information
you want to share with the world about graphic lcd panels, let me
know, and I'll post it on my website.  It will be a new section I
will add.  Anytime that anyone comes up with new data, give me a
copy of it, and I'll post it for all to use.   Hopefully, this way,
everyone will have access to LCD panel information they need to use
the surplus LCD panels in their projects.

What do you think?  Would it be worthwhile?  Anybody want to
contribute?   I have a couple of datasheets I'll start with.
I'll be putting them on my website within the next few days.
I'll let everyone know when they are there.

Contact me if you have anything.


                                               Regards,

                                                 Jim

James:

Look at my web page at  http://www.idcomm.com/personal/ottosen/   under
"Display large characters on a graphic LCD". There is some SX code as
well as a a PDF of some data sheets. The LCD's are not the notebook type
but the information may still be of interest. Feel free to link to the
site or copy the information to your site if it suits your fancy.

I've already been there.  Most of what they have is theory,
and data for their own products.   What I propose is a
stockpile of data for graphic panels by such manufacturers
as SHARP, TOSHIBA, SONY, etc.   I'm talking about data
such as pinouts of the connectors, electrical specs, timing
diagrams and data, etc.   Things that are hard to find.
I'll eventually get there.  It'll just take some time.

BTW, thanks for the link.

'[OT]: Good (any) resource for LCD datasheets?'
2001\06\29@055736 by Kevin Olalde
picon face
I've got an LCD recently pulled from a defunct office phone.

A sticker on the back reads:
UC24202
GNAR4PA
000717

Samsung is printed on left side of the board and 2154A is printed on the right.
There's two chips, but they're covered with a black substance (on PCB
packaging?).
With a 14 pin ribbon connector.

From web searching I *think* this may be similar to a Sieko L246200J000, but I'm
just guessing?

Anyone know where I can find a datasheet?

Thanks for any help,
Kevin

Can you tell how many lines/chars it is ? 16 x 1 ? If so, probably
a 44780 + 44100 combo, in which case the pin-out for the cable
is pretty standard. You may be able to trace the 0V line to the
PCB (sometimes it's marked on the PCB) for a clue or get the
black stuff off the chips to be really sure

I've never seen it operate, but by looking I'd guess 24x2 (maybe coincides with
the 24202 in the sticker?).

So scraping this black stuff off won't damage the chips?

24x2 sounds a bit much for just 2 chips. IF they are a 44780/4410
type pair you'd expect each to handle 16 chars at most. By looking
across the display in the right light you should be able to make out
how many chars it is
>

Are they actually SMT chips ? About an 80 pin FP80 or FP80A ?
I don't want to put you wrong if these are encapsulated (ie a die
under a blob), tampering with which will cause damage if you
try to get at them. Unless they really are ICs in the conventional
sense, I wouldn't attempt to uncover them - there won't be info
to read anyway. So, if they are encapsulations, that leaves you
with identifying any connections, comparing it to a typical 14-pin
header and taking your chances, which should be pretty good

More important is the chip number.  My guess is you will need to interface
with the chip and not the panel.

Assuming that these displays were produced in large quantity, the chips may
actually be bare die wire-bonded to the PCB rather than packaged parts.

Chip-on-board (COB) assembly is pretty common in high-volume production. If
the 'black stuff' (epoxy, IIRC) is a thin lump and has a smooth profile, I'd
bet it's been done that way.

Maybe I'm getting near bi-focal age, but after a few attempts at getting the
"right light", I'm pretty sure it's 24x2.

> Are they actually SMT chips ? About an 80 pin FP80 or FP80A ?

80 pins each looks about right.  The black blobs are about .5" square, I think I
can see the outline of one of the chips in the 'blob', looks to be about 1/2 the
size of the outer black square.  This stuff certainly doesn't look like it was
ever intended to come off.

"Die under a blob", that sounds like a it.

, tampering with which will cause damage if you

Yep, I'm leaving them in place.  Frankly if I needed to remove this stuff, I'd
rather just buy a new display.

OK

I have stripped LCD text displays from all sorts
of old equipment, phones, faxes, copiers, etc.

The usual indicator is check if it has a 12 pin
connector (or 14pins with led backlight) and if
so they usually work with the standard 44780
signal driving it. Some chipsets are not perfectly
compatable but will work ok with the 8-bit interface
on the standard 12pin connector.

one thing i've done before is to look up the driver chips on the back,
you can often find their pinout and follow the traces to the connector.
i even found that one 4 bit lcd i had could be sent 8 bits at a time if
i added the extra connections (the chip could do either).

'[EE]: Samsung LCD Datasheet'

Hi,

I was wondering if someone has a datasheet for a Samsung 16 character
LCD. I tried googling for it, but the only thing I could find is that it
is made by Samsung.

The Namr is VHC 16100 NBR, single line LCD w/out backlight, and it was
part of a Samsung SF-5100 LED Fax machine.

The problem is, I reaaaaally don't want to mess up Vss and Vdd... ItE
got a typical 14 pin arrangement, but I've got some datasheets for other
LCDs that read pin 1 as Vcc and some that read pin 1 as Vss...

Any clues?

Thanks,

Ricardo Medina

I bought one of these on ebay recently, with no pinout information. What I

Couple of simple methods:

1)
The metal bezel that supports the glass is usually connected to Vss.  Quick
check with an ohmmeter should tell you . . .

2)
 connect ohmmeter in "diode check" mode across the two pins you think are
Vss & Vdd.  One polarity should show about 0.7V drop, the other polarity
should show much higher - possibly even open.  The higher reading shows the
correct polarity.

'[OT] Where to find OPTREX DMC-16237 LCD Datasheet'
2005\07\08@113439 by o Yipmantin

I will be very pleased if any one can tell me where to find pin out
information of the OPTREX DMC-16237 LCD or similar. It has two chips
HD44100H and HD4478A00.
Also have 16 pins in 3 groups: 8 pins, 6 pins and 2 pins from left to
right front view.

'[EE]: LCD data wanted (also Siemens OPe pods)'
2005\09\18@153848 by Philip Pemberton
face picon face
Hi,
 Does anyone happen to have any data on either of the following LCDs?
 
1) Hitachi SP21H002-Z1A. CCFL backlight, unknown resolution. About 30 pins on
  a flexcable connector. Graphics type, chip-on-flexcable.
2) Siemens/URT UMS-7011JD-YG. 16-pin 0.1" connector. Unknown resolution,
  believed to be graphics type, two blob-top controller ICs on the back.
  I've worked out the power pins, data pins and the LED backlight pin based
  on the board it was plugged into (see below), but I'm still stuck trying
  to find out what controller it uses and what the 4 remaining unknown pins
  do.

The UMS-7011 came out of a Siemens "OPe" 6SE9590-0XX87-8BF0 wall-mount
controller module. The module won't power up - it seems to be waiting for
some data to be sent over the RS232 (or RS422) bus before it will display
anything on the LCD panel. Does anyone know what protocol these things speak?

Thanks.

'[EE]: LCD data bus with internal pullups'
2006\01\04@063510 by Steve Smith

I have a 16x2 display (varitronics MDLS16265......) and it appears to have
an internal pull up on its data lines. Its causing all sorts of stress in
this application as I have a resistive coupled keyboard on the same bus is
there any way of turning it off??? I have checked the data and it just
refers to the HD44780 for function which doesn't mention it there is 100k
pull down on the bus and the pin voltages sit at about 4.2v about 42uA per
pin pull up. Hence my 10K coupled buttons stop working when the display is
installed !!!!!!!!!!!

I know change the resistors but not an option until Monday !

Anybody got any ideas???

It does, in a very implict way. First it shows no connection at all to
the lower data bus pins when 4-bit mode is used (this is bad practice
unless some form of pull up or down is present), and in the electrical
section the strength of these pulls is documented.

> Anybody got any ideas???

Put a buffer inbetween. Or are there pull up/downs on all data pins or
only on D0..D3? If only on the lower pins you could use 4-bit mode.

Evening all..

Does anyone have a secret source of LCD datasheets because i am  
buggered if i can find any. Trying to find info about either a sharp  
lm80c031x  or a samsung lt121su-121 LCD panel. Have tried google and  
all the sensible places to look so i am either stupid or nobody knows  
how they work. Would be grateful of any info as ever.. thanks..

You need to check the number on the controller chip and search for that rather than the part number of the entire LCD panel.

Depends what type of panel you're talking about - for things like TFTs, the interface is one of a
small handful of types, but what you need is to identify which type, and get the pinout & connector
type.

Advantech used to have a big list of the above for info on connecting to their LCD controllers, but
has either moved or disappeared now - might be worth hunting around to see if it's still there
somewhere.

One of my colleagues has a panel where this would be impossible - the chips
are COB blobs of plastic. You need the panel number to find the interface
chip type, and from there search for the relevant chip data.

As both of these appear to be for production laptops, I doubt you will find
useful info, unless you can identify likely driver chips on them, as has
already been mentioned (and which I sort of rebuffed).

I have this as a very rusty bookmark

http://eio.com/frumindx.htm

Haven't used it for ages, but it was very helpful at one time getting
datasheets. Can't hook up to it this morning for some reason

I too want to get the same data out of the same electronics or display interface.


PJV has said that he:


I made an interface with an SX52 to selected display segments, those were all being clocked at 1 mHz as I recall. Quite a bit of trickery capturing the desired segments .... there were tons (256?) of them, and then mapping those into a table to generate machine readable distances. Ended up working pretty well.
Peter (pjv)

If possible I would like to get hold of your work for decoding display with SX...

please.
